Answer: A-balanced

Explanation:

An ecosystem is the community where living beings interact with their non-living environment so as to sustain and survive. The dynamics and structure of the ecosystem changes according the abiotic (non-living) and biotic (living)  factors.

The ecosystem remain balanced due to these changes. For example natural calamity such as flood being an abiotic factor will be responsible for controlling the population of overcrowded habitat. Also the population of predators will control the growth and abundance of prey species.

In 1.71 minutes, a ski lift raises four skiers at constant speed to a height of 148 m. The average mass of each skier is 62.9 kg
Vitek1552 [10]

Answer:

3560.36 Watts

Explanation:

Power, P=\frac {nΔW}{Δt) where P is power, n is the number of skiers, t is time in seconds and Δt is change in time, ΔW is given by mgh where m is mass, g is gravitational constant, h is height

Substituting n for 4 skiers, m for 62.9 Kg, g for 9.81, h for 148 m and t for 1.71*60=102.6 seconds

P=\frac {4*62.9*9.81*148}{1.71*60}=3560.360702  Watts

Average power is approximately 3560.36 Watts
